Answer:
C
Step-by-step explanation:
We know that function <em>h</em> represents an object's height in feet after <em>x</em> seconds.
In that case, option A) h(15) = 100 means that after 15 seconds, the object's height is 100 feet.
Option B) h(100) = 15 means that after 100 seconds, the object's height is 15 meters.
Therefore, neither A nor B are correct.
Option C) h(15) - h(0) = 100 means that between the zeroth and 15th second, their difference is 100 feet.
In other words, the object's height increased by 100 feet over the first 15-second period.
Option C is correct.
For Option D), it gives us the average rate of change. (h(15) - h(0)) / (15) = 100 means that for the first fifteen seconds, the height of the object increased at an average rate of 100 feet per second.

Step-by-step explanation:
![7x - 15 + x= 180 \\ 8x = 180 + 15 \\ 8x = 195\\ x = 24.375 \\ x + 28 + 4x - 3 + 24 = 180 \\ 5x = 180 - 28 + 3 - 24 \\ 5x = 131 \\ x = 26.2](https://tex.z-dn.net/?f=7x%20%20-%2015%20%2B%20x%3D%20180%20%5C%5C%208x%20%3D%20180%20%2B%2015%20%5C%5C%208x%20%3D%20195%5C%5C%20x%20%3D%2024.375%20%5C%5C%20x%20%2B%2028%20%2B%204x%20-%203%20%2B%2024%20%20%3D%20180%20%5C%5C%205x%20%3D%20180%20-%2028%20%2B%203%20-%2024%20%5C%5C%205x%20%3D%20131%20%5C%5C%20x%20%3D%2026.2)

Answer:
![V= 2x^3](https://tex.z-dn.net/?f=V%3D%202x%5E3)
The volume is 128cm^3
Step-by-step explanation:
Given
![Cubes = 2](https://tex.z-dn.net/?f=Cubes%20%3D%202)
![Sides = 4cm](https://tex.z-dn.net/?f=Sides%20%3D%204cm)
Required
Determine an expression for its volume
Find the volume
Volume of a cube is:
![Volume = x^3](https://tex.z-dn.net/?f=Volume%20%3D%20x%5E3)
Where x represents the length of a side
So, volume of 2 cubes would be:
![V= x^3 + x^3](https://tex.z-dn.net/?f=V%3D%20x%5E3%20%2B%20x%5E3)
![V= 2x^3](https://tex.z-dn.net/?f=V%3D%202x%5E3)
Solving (b): Volume when x = 4
Substitute 3 for x in ![V= 2x^3](https://tex.z-dn.net/?f=V%3D%202x%5E3)
![V = 2 * 4^3](https://tex.z-dn.net/?f=V%20%3D%202%20%2A%204%5E3)
![V = 2 * 64](https://tex.z-dn.net/?f=V%20%3D%202%20%2A%2064)
![V = 128](https://tex.z-dn.net/?f=V%20%3D%20128)
<em>Hence, the volume is 128cm^3</em>
